Previously, Japanese toy making and video game company Bandai has released two devil fruits: Mera Mera no Mi (メラメラの実) and Ope Ope no Mi (オペオペの実) for their One Piece fans. Recently, It's time for Gomu Gomu no Mi (ゴ ム ゴ ム の 実) which is scheduled for release in July 2016. Bandai is now taking orders through its online store. http://p-bandai.jp/

The scale of Gomu Gomu no Mi is 1/1 (Life-size), that means it's actually the same size as you've seen in One Piece manga and anime series. The devil fruit material is PVC (Polyvinyl chloride), an advantage of PVC is easy to clean. Bandai's Gomu Gomu no Mi devil fruit is priced at 3,780 Yen. I'm quite satisfied with the price when compared to the overall design, size and material).
